Description

Technical Field

[0001] The present invention relates to the technical field of porous workpiece processing, and more specifically, to an on-line detection and punching system based on porous workpieces. Background Art

[0002] Mylar sheet (MYLAR sheet) PET polyester film is a film formed by heating dimethyl terephthalate and ethylene glycol with the assistance of relevant catalysts, through transesterification and vacuum polycondensation, and biaxial stretching. The Mylar punching equipment is mainly used for precision hole processing in the fields of electronics, optics, electrical insulation, etc. The core requirements include high-precision, non-damaging processing, and the ability to adapt to complex hole shapes.

[0003] Currently, when punching Mylar sheets, it is generally necessary to perform multi-hole synchronous punching operations, including single-piece punching operations and continuous punching operations in a unwind mode. During continuous punching operations, due to a large number of hole positions, errors will occur during the continuous punching process due to errors generated when the equipment transports the Mylar tape, resulting in gradual deviation of the hole positions. At the same time, for the detection of punching quality, such as the detection of residues inside the holes and the smoothness of the hole edges, when the hole position error and the punching quality do not meet the standards are detected, it is necessary to stop the machine for re-calibration and then restart the operation, resulting in a reduction in the operating efficiency of the equipment.

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention;

[0027] Please refer to Figures 1-6, in the present invention, for an on-line detection and hole-opening system based on a porous workpiece, a longitudinal driving rail 2 is installed at the top inside the box body 1, a vertical cylinder 3 is installed on the longitudinal driving rail 2, a punching member 4 is installed at the bottom of the vertical cylinder 3, two guiding members 5 are installed inside the box body 1, a support seat 6 is fixedly installed inside the box body 1, the support seat 6 is located between the two guiding members 5, a pay-off reel 7 is installed on the left side of the box body 1, through holes 8 are formed on both sides of the box body 1, a fixing frame 9 is installed on the right side of the box body 1, an industrial CT machine 10 is installed inside the fixing frame 9, a driving and guiding roller 11 is installed inside the fixing frame 9, and a take-up reel 12 is fixedly installed at the right end of the fixing frame 9.

[0028] The punching member 4 includes a fixing plate 41, punching heads 42 arranged in a matrix, and a pressing member 43. The top of the fixing plate 41 is fixedly connected to the vertical cylinder 3. The punching heads 42 are fixedly installed at the bottom of the punching member 4 in a matrix distribution. The pressing member 43 is installed on the fixing plate 41, and the pressing member 43 is movably matched with the punching heads 42.

[0029] , in the present invention, with the box body 1 as the main body of the device, first, the mylar film roll is installed on the pay-off reel 7, then the end of the mylar film is led out, passed through the left through hole 8 into the inside of the box body 1, then passed through the inside of the left guiding member 5 in sequence, passed through the support seat 6 and then through the right guiding member 5, and then passed through the through hole 8 on the right side into the inside of the fixing frame 9, passed under the industrial CT machine 10, and finally passed through the driving and guiding roller 11 and is wound by the take-up reel 12.

[0030] When the device is running, first start the take-up roller 12 and the pay-off roller 7 to drive the mylar sheet to move intermittently. Then start the vertical cylinder 3 to cooperate with the pause frequency of the mylar sheet to drive the punching member 4 to move vertically back and forth, so as to continuously punch the mylar sheet. After the punched mylar sheet is led out by the right guide member 5 and enters the inside of the fixing frame 9, it is photographed and detected by the industrial CT machine 10 to detect the hole position and hole quality. The detected pictures are sent to the external control terminal for rapid analysis.

At the same time, for the detection of punching quality, such as the detection of residues in the hole and the smoothness of the hole edge, when the hole position error and the punching quality do not meet the standard are detected, it is necessary to stop the machine for re-calibration and then restart the operation, resulting in a reduction in the operating efficiency of the device.
